Chelating Agents for Land Decontamination Technologies by Daniel C. W. Tsang, editor, Irene M. C. Lo, Rao Y.

By Daniel C. W. Tsang, editor, Irene M. C. Lo, Rao Y. Surampalli

Chelating brokers for Land Decontamination applied sciences examines the appliance of chelating brokers for the therapy of soil infected with metals. infected land remediation is a common and dear challenge, and the normal excavation-and-disposal therapy procedure isn't really a sustainable answer. Chelating brokers (organic compounds which may bind steel ions) are an enticing new expertise for land decontamination, simply because chelating brokers increase steel extraction from infected soil or sediment and facilitate steel mobility in subsurface soils. Chapters during this booklet hide the method basics in addition to engineering purposes and up to date advances for using chelating brokers in soil washing, soil flushing, phytoremediation, and electrokinetic remediation. They deal with the applying of chelating brokers for either ex situ and in situ soil remediation applied sciences. The huge use of illustrations and precis tables is mixed with updated references. This compilation of engineering functions and study findings for various chelating agent stronger remediation applied sciences may be valuable to environmental engineers, scientists, and determination makers concerning infected land remediation
